![]() ![]() ![]() The ability of two outputs to be mixed by simply tying them together will also be a function of (at least) the relative output levels of the two signals and the output impedance of the two signal sources. That being the case, what is the right stage to tie these things together? Both of them just feed the output jack?įurther research SEEMS to indicate that pretty much any preamp (whether on an active pickup or in a piezo preamp) is concerned with input impedance, but then matches it to "line level While a blend pot could be interesting, I'm fine with just two separate volume controls to create my "blend". maybe that's too much to hope for?Īssuming they are a match, this means that each respective system essentially has its own master volume. but I'm hoping that since both systems are active, at the output stage there's going to be a match. I don't know if the impedances of the magnetic and piezo systems are going to be an exact match because they don't seem to list the impedance of these cheap acoustic preamps. We'll see if I can find one that fits otherwise I might be back to square one.Īssuming the components work out, the piezo elements "tie" together and feed into the preamp, which has its own output. On the piezo side, I haven't actually procured anything yet preamp-wise, but I was thinking of grabbing the smallest acoustic preamp I can find, and finding some space for it, maybe with the panel facing outwards on the back of the guitar. So, a master volume and a master tone that I'd probably rarely use, and a push/pull dedicated to each EMG. ![]() For the magnetic system, the plan is to use the push/pull as 1V, 1T and ditch the normal pot. I have 2 25K push/pull pots for mode switching ("coil splitting") duty, plus an extra "normal" 25k pot that was originally meant for tone. On the magnetic side, I have an EMG 89 and 81TW, Both are dual mode (quasi-coil-split). Although blended piezo and magnetic systems seem to have entered a fairly mainstream space right now, I can't seem to find many diagrams to achieve what I'm after. ![]()
